Hutchinson-Gilford progeria syndrome is a genetic condition characterized by the dramatic, rapid appearance of aging beginning in childhood. Affected children typically look normal at birth and in early infancy, but then grow more slowly than other children and do not gain weight at the expected rate (failure to thrive).

They develop a characteristic facial appearance including:

• prominent eyes,
• a thin nose with a beaked tip,
• thin lips, a small chin, and
• protruding ears.

Hutchinson-Gilford progeria syndrome also causes:

• hair loss (alopecia),
• aged-looking skin,
• joint abnormalities, and
• a loss of fat under the skin (subcutaneous fat).

This condition does not disrupt intellectual development or the development of motor skills such as sitting, standing, and walking.

This condition is very rare; it is reported to occur in 1 in 4 million newborns worldwide. More than 130 cases have been reported in the scientific literature since the condition was first described in 1886.

Mutations in the LMNA gene cause Hutchinson-Gilford progeria syndrome.

The LMNA gene provides instructions for making a protein called lamin A. This protein plays an important role in determining the shape of the nucleus within cells. It is an essential scaffolding (supporting) component of the nuclear envelope, which is the membrane that surrounds the nucleus. Mutations that cause Hutchinson-Gilford progeria syndrome result in the production of an abnormal version of the lamin A protein. The altered protein makes the nuclear envelope unstable and progressively damages the nucleus, making cells more likely to die prematurely. Researchers are working to determine how these changes lead to the characteristic features of Hutchinson-Gilford progeria syndrome.
